I recently saw a Facebook post about a marathon handing out coke at one of their aid stations. In the comments section, some runners swear by it, others say it’s a GI disaster waiting to happen. So… what’s the truth?

In this episode, we break down the science of fueling your runs with a sugar-sweetened beverage like Coke — how it compares to sports drinks like Gatorade, what happens in your gut when you drink it mid-run, and when it might actually work as a budget-friendly option.

You’ll learn:

  • How Coke stacks up nutritionally against Gatorade

  • Why its might not actually be the best kept secret in marathon nutrition

  • How to safely experiment with it (if you want to try!)

  • Tips for balancing your fluids and electrolytes during long runs
